(analytical)The revaluation of leisure in family contexts, caused by lockdowns imposed during the COVID-19 pandemic that led to an increase in time spent at home, has contributed to this area emerging as a focus of educational research, which until now had been neglected in Spanish-speaking countries. In the present study, the authors present the process of designing and validating a "Questionnaire on family leisure during lockdowns”. In order to provide content validity and consistency to the designof the instrument, feedback from 10 experts assessed the clarity, relevance and suitability of the instrument using a validation scale. The results show that the questionnaire, with 61 questions, has sufficient psychometric properties that make it an appropriate tool to evaluate family leisure. During this process the authors confirmed its rigor and value as an analytical instrument for research.
